Specification of Letters-Patent; Patented June 15 1920.

Application filed December 2, 1919. 7 Serial No. 341,916.

To all whom it'mag concern:

Be it known that I, HERBERT J. GWYER, a citizen of theUnited States of America, residing at Yonkers,.Westchester county, New

York, have invented a new and useful .Cor-

ner Connection for Cabinets,'of which the following is a specification.

My invention relates to novel corner fastening means for frames such as provided around the edges of panels. In such constructions, it is important "that the corners of the frames should be very securely and the top and bottom panels are to be screwed or bolted to adjacent side panels, and my present improvement provides not only connecting means for the'corners of the top and bottom panels, but it also provides protected passages through said corners for the purpose of receiving the fastening screws or bolts, thereby making it unnecessary to form separate passages and to provide additional protecting means for the same. From the foregoing, it will be apparent that the objects of my invention include simplicity of construction, economy, strength, and durability. v

In the drawings, Figure 1 is a plan view of a corner of a frame equipped with my invention. I

Fig. 2 is a view of the underside thereof.

Fig. 3 is a section on the line 33 of Fig. 2.

Fi s. detai s. 1-2 represent the two ends of two panel framing pieces which are mitered so as to come together at the proper angle. In the particular construction shown, the undersides of the framing pieces are longitudinally grooved to receive the edges of the side box anels of a cabinet or box. At the 'meetmg line of the mitered ends of the pieces 1 and 2 is formed a hole or passage.

4 and 5 are perspective views of 3 represents ailocking piece for'the topside of the framing pieces, the same being preferably in the form of an annular washer centrally countersunk,-and provided around its outer edge with a depending fiange, the

lower edge of which is preferably provided wlth spurs M. This locking piece is drlven into the material of the framing pieces 1 and 2 in such a position as topartially overlap each piece and so thatthehole in the locking piece will be concentric with the passage through the mitered corners. 5 is a complementary locking piece which is preferably angular in outline so as to fit into thegrooved underside of'the framing: 170

pieces 1 and 2 in the manner shown in Fig. 2'. This second piece is likewise preferably provided with a flange around its edge which may also have spurs 6-6. The

second locking piece 5 also has a hole which registers with the bore through the framing pieces. The second locking piece 5 is like-- wise driven into the wood of the framing 7 pieces so as to become interlocked therewith.

It will be seen that the locking piece 5 not only holds the members 1 and 2 together by reason of the fact that the edge thereof is driven into the material of both of said members, but its design is such that it acts as an angular key when seated in the 'bot- 86 tom of the angular grooved portion at the underside of the corners of the frame.

Both of the locking pieces 3 and 5 may be economically produced from sheet metal.

Added security may be had by providing 90 means to tie the locking pieces together, which means is. preferably in the form of a tube 7, which may be passed through the holes in the locking pieces 3--5 and through the passage in the frame, the ends of the said tube being upset outside of the members 3 and 5 so as to rigidly connect said two locking pieces. This tube 7 not only acts to tie the locking pieces together, but

it also serves as a means to protect the pas- 10 sage through the frame and as a guide-way for the fastening screw and'bolt, theWlatter' being designated at 8 in Fig. 3.

When a cabinet or box is constructed with bottom and top panels having corners com structed in the manner illustrated in the ac companying drawings (the said top and bottom panels being spaced by the usual side panels), a fastening means 8 1n the form of a bolt may be {passed entirely through the assembled structure at each con ner so as to tie together the top and bottom panels in a most effective manner.

What I claim is 1. In a frame of the character described, tWo framing pieces meeting at an angle, means for connecting said framing pieces at the meeting line comprising tWo complementary metallic locking pieces, arranged on the top and bottom of the frame and each partially overlapping each of said framing pieces at the meeting angle, each locking piece having a hole therein, a passage through the corner of the frame at the meeting line registering With said holes in the locking pieces With means on each of said locking pieces to be driven into the material of said framing pieces to secure the parts together, and a tube passing through said locking pieces and upset outside of the same. o v V u 2., 'A structure such'as described in claim 1-, thelocking piece on the underside of the frame being of an angular outline.

3. In a framefor box panels or the like,

tWo framin ieces meetin at an an -le a 2-. b g a passage extending through said framlng pieces at the meetlng line, tWo complementary metallic locking pieces each having a hole therethrough, arranged to register With said passage through the frame and 101 cat-ed respectively on the top and bottom of sald frame, spurs on each'of said locking pieces, said spurs penetrating into the material of said framing pieces, the top locking piece being countersunk, a metallic tube forming a lining for the passage through said framing pieces and upset outside of said locking pieces to tie the same together and to form a guide passage for a bolt or screw.

4. A frame construction such as described "HERBERT J. IVGWYER.
